INGOT- MOLD.

- SPECIFICATION forming part of Letters Patent 110.354,?42, dated December 21, 1886.

Application filed August 8, 1886. Serial No. 939,833. (No model.)

In the accompanying drawings, which illus trate the invention, Figure 1 is a front broad side View of the mold. 'Fig. 2 is an edge or,

1 narrow side View of the mold, showing the means for clamping the two sections. Fig. 3 is an end view of the mold and clamps, showing the two mold-sections ready for filling. Figs. 4, 5, 6, and 7 are detail views of the improved clamping device. Fig. 8 is a vertical cross section through one of the bolts, the wedges, and the flange of the mold.

The letter A designates one section, and B the other, of a metal mold. These two sections unite at the narrow sides, which are opposite,

and said sections are separable at the uniting edges 0 on said narrow sides. The confronting faces of the uniting edges 0 of the two sections havea groove, 0, for a packing of sand or clay,

by which the joint at the uniting edges may be made impervious to the molten metal.

The two narrow sides of each mold-section A B are each provided with a flange, d, which is shown extending the length of the mold that is, from top to bottom. While it is deemed preferable for these parallel flanges to extend the whole length it is not essential.

Each flange stands back from the uniting edge 0, whereby when the two sections are together the two parallel flanges at one side do not a touch each other, but are separated by a space,

0. By this construction the flanges do not get so hot as they would, and neither do the uniting edges 0. Boltsfpass through the two +5 parallel flanges d, and' across'the space a at each side of the mold, and unite or hold the two mold-sections together. I have deviseda wedgeclamp device for quickly loosening the two mold-sections either to permit the extreme 5o expansion of metal that ensues when all the parts are highly heated, or to allow the ingot- [casting to be removed from the mold. This wedgeclamp device comprises two upright movable bars, Gone at each'narrow side of the mold-each bar being provided on one side with two or more inclined blocks, h, the point ends of which are downward.

The inclined blocks it (see Figs. 5 and 6) are partly divided up and down the center by a slot, f which opens entirely through the bar G. The bar at its upper end has a hole, i. Each bolt f carries aloose wedge or inclined block, k, which is in position to confront one of the innation of the loose blocks is being reverse to the-inclination of the blocks h, as shown in Fig. 2.

Each loose block (see Fig. 4) has a bolthole, f, and on the inclined side is provided with a lug, Z, which, by coming in contact with the block on the bar G, prevents the loose one from turning. When two confronting blocks, h k, are in contact, as here constructed, the slot f in one will be occupied by the lug Z on the other, whereby the block which is loose on the bolt f is prevented from turning.

Another feature is shown in Fig. 7. The outer side or straight face of the loose block has a concavity, it, about the bolt-holef, and the nut 0 on the bolt has one side, a, convex. By this construction the convex side of the nut bearsin the concavity of the loose block, and the bar G may be moved up or down without liability of the loose block is getting out of true with respect to its confronting block h.

It will be seen that one of the inclined blocks of each wedge-clamp is attached to the movable bar G, and this affords an important advantage. When the mold is filled with hot metal,and expansion of the mold parts ensues, this expansion may be relieved a little at a time and as gradually as may be needed. by simply drawing the bar G upward. A very small movement of this bar will somewhat loosen the clamps and afford some relief to the pressure due to expansion. The bar may be moved up by inserting the end of a rod in the hole at the upper end and using such rod as-a lever to lift the bar. As the .bolts f pass through the upright bar G, the vertical slots f in said bar are necessary to permit it to be raised or lowered.

clined blocks h on the movable bar, the inclii Having described my invention, I claim and desire to secure by Letters Patent of the United States- W 1. An open-top mold for ingots made in two sections, A and B, separable on opposite sides, and each section provided on its separable side with a flange, d, the two flanges on each side being parallel, in combination with two upright movable bars, G, one at each separable side of the mold, and each of said bars provided with two or more inclined blocks, 7:, all having their point end downward and having avertical slot, f, a reversely-inclined block, k, confronting each inclined block on the said upright bars, and a bolt, f, passed through each two inclined blocks, the two parallel flanges and the upright movable bar, whereby upon raising or lowering the upright bars the two moldsections will at once be loosened or tight- 20 ened, as set forth. 1

2. An open-top mold for ingots made in two sections, A and B, separable on opposite sides, and each section provided on its separable side with a flange, d, in combination with a wedge JOHN SABOLD.
